The older PC in my guest room has an HDD that's failing so would like to upgrade it to an SSD, but prices on those are very high right now.

Is there a reliable M2 SSD (can be PCIE 3--but would prefer 4 to future proof it?)

Eventually, I'll probably build a new pc but for now this one is working ok.

Alternatively, I do have a new WD Blue HDD that I could use instead considering how high the SSD prices are.

Budget under $150.
